Features:

Sturdy branch hook - After pruning, loose clippings can be easily removed from the tree with the branch hook.
STIHL EC-motor - The STIHL brushless electric motor (EC) is very energy efficient and practically maintenance-free. Thanks to its outstanding efficiency, the battery power is directly translated into impressive performance. During operation, the electronically controlled EC motor permanently monitors the load and adjusts the engine accordingly.
Ergonomic control handle - The HTA 66 has a locking lever (orange front), ERGO lever (black) and main trigger lever (orange below). The locking lever is self-resetting and prevents unintentional switching on of the device. When the ERGO lever and shift lever are pressed, you can work continuously with ease.
Perfectly balanced - The battery in the shaft of the HTA enables balance during use and allows for fatigue-free work.
Sidechain tensioner - The chain tensioner is located on the side to prevent contact with the chain when adjustments are made.
Tool-less oil cap - Patented cap for the oil tank, the tank can be quickly opened and closed without effort and tools.
